Seed dispersal

How do plants reproduce?

Acorns fall from the tree and sprout

• If they are not destroyed by animals, white oak acorns can sprout rapidly after falling from the tree.

Animal dispersal by hooked fruits

• Some species of plant use hooks on their fruits to attach themselves to the fur of mammals or feathers of birds

Animal burial

• Hard nuts are usually destroyed if chewed or eaten.

However, animals such as squirrels may store them to eat later and forget to go back to get them, giving them a chance to germinate.

• On rare occasions, birds such as blue jays can transport acorns long distances.

Soft fruit dispersal

• Fleshy fruits

• The seeds of many plants are dispersed after passing through the digestive system of animals that have eaten the fleshy fruits.

Wind dispersal

• Some plants, such as the dandelion, have seeds that act as parachutes, which are carried away by the wind

Plantlet reproduction

• Spider plants, amongst others, send out stems which produce plantlets, these baby plants then try to root themselves

Spinning dispersal

• Maple fruits are winged, twoseeded pods. They spin like helicopters as they fall from the tree, providing a longer time for dispersal by wind.
